Answer:
Step-by-step explanation:
<u>Surface Areas
</u>
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is
The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus
The back left area is another rectangle of 4.5 mm by 9 mm
Finally, the back right area is a rectangle of 6 mm by 9 mm
Thus, the total surface area of the prism is
We know, Area = Length * Width
So, with area 42, dimensions could be: 1 * 42
2 * 21
3 * 14
6 * 7
Just draw the lines with that measures, two pair of two equal opposite lines.
Hope this helps!
Answer:
maybe (2,8) but im not so sure im kinda okay at math
Step-by-step explanation:
-3/7 is obviously the least because it is a negative number.Then 2/5 because if you think about it if 2/5 is 2 of 5 equal pieces. 2/3 is 2 of 3 pieces.So if you think about a pizza if you cut the pizza into 3 pieces and ate 2 imagine how much you would have left and then think about cutting the pizza into 5 pieces and only eating 2 . Think about that. So the answer in the end is -3/7,2/5, and then 2/3. Hope I helped!
The difference between the x-coordinates of the points given is 3, and none between the y-coordinates, so the side of the square is 3. Square 3 and get the area, 9 units squared.
